Product Description

The Air Lift 88377 LoadLifter 5000 Ultimate is a heavy-duty rear air spring kit engineered specifically for the Ram 1500 TRX (2021-2024) and Ram 1500 RHO (2025-2026). It delivers up to 5,000 lbs. of load-leveling support to keep your truck level and stable when towing trailers or hauling heavy payloads. The internal jounce bumper acts as a secondary shock absorber, protecting the system even at zero PSI and preventing harsh bottom-outs.

What sets this kit apart is the included Air Spring Cradles - a feature that allows the air springs to detach from the lower bracket, maintaining full suspension travel for serious off-road articulation. Whether you're overlanding or running trails, the suspension won't be compromised. Installation is straightforward with no frame drilling required, and all corrosion-resistant mounting hardware is included. Backed by Air Lift's Limited Lifetime Warranty, this kit is built for drivers who demand maximum capability from their truck.
